A second axial securing of the housing 16 is designed such that it compresses a second predetermined portion 24 of the housing 16 when mounted on the outer conductor part 10.

Wie insbesondere aus Fig. 1, 3, 4 und 5 für die beispielhaft dargestellte, bevorzugte Ausführungsform des erfindungsgemäßen HF-Steckverbinders ersichtlich, umfasst die erste axiale Sicherung zwei in Umfangsrichtung an gegenüberliegenden Seiten jeweils teilweise umlaufende Erhebungen 20 in dem Bereich 36 des Außenleiterteils 10, welcher in die Durchgangsbohrung 18 des Gehäuses 16 eingreift. Diese Erhebungen 20 sind derart ausgebildet, dass ein Außendurchmesser des Außenleiterteils 10 im Bereich der Erhebungen 20 größer ist als ein Innendurchmesser der Durchgangsbohrung 18 des Gehäuses 16 im Bereich des ersten vorbestimmen Abschnittes 22. Auf diese Weise wird das Gehäuse 16 beim axialen Aufschieben des Gehäuses 16 auf das Außenleiterteil 10 bis zur gewünschten Position im Bereich des ersten vorbestimmen Abschnittes 22 radial nach außen gedehnt. Die sich dadurch ergebende, radial nach innen gerichtete Kraft aufgrund der radialen elastischen Dehnung des Gehäuses 16 hält das Gehäuse 16 auf dem Außenleiterteil 10 fest und sichert das Gehäuse 16 gegen axiales abziehen vom Außenleiterteil 10.As in particular from Fig. 1 . 3 . 4 and 5 for the exemplified, preferred embodiment of the RF connector according to the invention, the first axial securing two circumferentially on opposite sides each partially encircling elevations 20 in the region 36 of the outer conductor part 10, which engages in the through hole 18 of the housing 16. These elevations 20 are formed such that an outer diameter of the outer conductor part 10 in the region of the elevations 20 is greater than an inner diameter of the through hole 18 of the housing 16 in the region of the first predetermined portion 22. In this way, the housing 16 during the axial sliding of the housing 16th to the outer conductor part 10 to the desired position in the region of the first predetermined portion 22 radially outwardly stretched. The resulting radially inwardly directed force due to the radial elastic stretching of the housing 16 holds the housing 16 firmly on the outer conductor part 10 and secures the housing 16 against axial withdrawal from the outer conductor part 10.

Wie insbesondere aus Fig. 1, 4 und 6 für die beispielhaft dargestellte, bevorzugte Ausführungsform des erfindungsgemäßen HF-Steckverbinders ersichtlich, umfasst die zweite axiale Sicherung zwei Paar krallenförmiger Erhebungen 26, welche sich in radialer Richtung von dem Umfang des Außenleiterteils erheben. Die beiden Paare krallenförmiger Erhebungen 26 sind an gegenüberliegenden Seiten des Außenleiterteiles 10 in dem Bereich 36 des Außenleiterteils 10 angeordnet, welcher in die Durchgangsbohrung 18 des Gehäuses 16 eingreift. Die krallenförmigen Erhebungen 26 eines Paares sind in Umfangsrichtung gesehen einander zugewandt und definieren zwischen sich einen Abstand 28 in Umfangsrichtung. Jede krallenförmige Erhebung 26 weist einen hakenförmigen Abschnitt auf, der von dem steckseitigen Ende 14 weg ausgerichtet ist. Der zweite vorbestimmte Bereich 24 des Gehäuses 16 umfasst vier sich an der Innenseite des Gehäuses 16 radial nach innen erhebende, sich jeweils in axialer Richtung erstreckende Stege 30 auf. Die Stege 30 sind in Umfangsrichtung gleichmäßig voneinander beabstandet, so dass beim axialen Aufschieben des Gehäuses 16 auf das Außenleiterteil 10 immer jeweils zwei Stege 30 zwischen zwei krallenförmige Erhebungen 26 eingreifen so dass das jeweilige Paar von krallenförmigen Erhebungen 26 mit einem der Stege 30 zusammenwirkt. Hierbei ist eine Breite der Stege 30 in Richtung senkrecht zur axialen Richtung größer als der Abstand 28 der krallenförmigen Erhebungen 26 eines Paares. Auf diese Weise pressen die krallenförmigen Erhebungen 26 die Stege 30 zusammen. Die sich dadurch ergebende Kraft zwischen den krallenförmigen-Erhebungen 26 und dem jeweiligen Steg 30 sichert das Gehäuse 16 gegen ein Abziehen vom Außenleiterteil 10 in axialer Richtung, da die Haken der krallenförmigen Erhebungen 26 in axialer Richtung von dem steckseitigen Ende 14 weg gerichtet sind. Durch die Anordnung von Paaren von krallenförmigen Erhebungen 26 und der Stege 30 kann das Gehäuse 16 mit verschiedenen Winkelpositionen relativ zum Außenleiterteil 10 auf dieses axial aufgeschoben werden. Gleichzeitig ist das Gehäuse 16 auch gegen eine Verdrehung in Umfangsrichtung relativ zum Außenleiterteil 10 gesichert.As in particular from Fig. 1 . 4 and 6 for the exemplified, preferred embodiment of the RF connector according to the invention, the second axial securing comprises two pairs of claw-shaped elevations 26, which rise in the radial direction from the circumference of the outer conductor part. The two pairs of claw-shaped elevations 26 are arranged on opposite sides of the outer conductor part 10 in the region 36 of the outer conductor part 10, which engages in the through-bore 18 of the housing 16. The claw-shaped elevations 26 of a pair are facing each other in the circumferential direction and define therebetween a distance 28 in the circumferential direction. Each claw-shaped elevation 26 has a hook-shaped portion which is aligned away from the plug-side end 14. The second predetermined region 24 of the housing 16 comprises four webs 30 which rise radially inwardly on the inside of the housing 16 and extend in each case in the axial direction. The webs 30 are uniformly spaced apart in the circumferential direction, so that when the housing 16 is pushed axially onto the outer conductor part 10, two webs 30 always engage between two claw-shaped elevations 26 so that the respective pair of claw-shaped elevations 26 cooperate with one of the webs 30. Here, a width of the webs 30 in the direction perpendicular to the axial direction is greater than the distance 28 of the claw-shaped elevations 26 of a pair. In this way, the claw-shaped elevations 26 press the webs 30 together. The resulting force between the claw-shaped elevations 26 and the respective web 30 secures the housing 16 against being pulled off the outer conductor part 10 in the axial direction, since the hooks of the claw-shaped elevations 26 are directed away from the plug-side end 14 in the axial direction. The arrangement of pairs of claw-shaped elevations 26 and the webs 30, the housing 16 can be pushed with different angular positions relative to the outer conductor part 10 on this axially. At the same time the housing 16 is secured against rotation in the circumferential direction relative to the outer conductor part 10.

Bei einer temperaturbedingten Aufweitung der Abmessungen des Gehäuses 16 bei höheren Temperaturen lässt die Haltekraft zwischen dem ersten vorbestimmten Abschnitt 22 des Gehäuses 16 und den Erhebungen 20 nach, da sich der Innendurchmesser des Gehäuses 16 im ersten vorbestimmten Abschnitt 22 vergrößert. Jedoch verstärkt sich gleichzeitig die Haltekraft zwischen den krallenförmigen Erhebungen 26 und den Stegen 30, da sich durch das temperaturbedingte Aufweiten der Abmessungen des Gehäuses 16 auch die Breite der Stege 30 erhöht. Somit ist auch bei hohen Temperaturen eine ausreichende axiale Sicherung des Gehäuses 16 gegen axiales Abziehen von dem Außenleiterteil 10 durch die zweite axiale Sicherung 26 in Zusammenwirken mit den Stegen 30 sichergestellt.At a temperature-induced widening of the dimensions of the housing 16 at higher temperatures, the holding force between the first predetermined Section 22 of the housing 16 and the projections 20, since the inner diameter of the housing 16 in the first predetermined section 22 increases. However, at the same time the holding force between the claw-shaped elevations 26 and the webs 30 increases, since the width of the webs 30 increases due to the temperature-induced widening of the dimensions of the housing 16. Thus, even at high temperatures sufficient axial securing of the housing 16 against axial withdrawal from the outer conductor part 10 by the second axial securing 26 in cooperation with the webs 30 is ensured.

Bei einem temperaturbedingten schrumpfen der Abmessungen des Gehäuses 16 bei niedrigen Temperaturen lässt die Haltekraft zwischen den krallenförmigen Erhebungen 26 und den Stegen 30 nach, da auch die Breite der Stege 30 schrumpft. Jedoch verstärkt sich gleichzeitig die Haltekraft zwischen dem ersten vorbestimmten Abschnitt 22 des Gehäuses 16 und den Erhebungen 20, da sich durch das temperaturbedingte Schrumpfen der Abmessungen des Gehäuses 16 auch der Innendurchmesser des Gehäuses 16 im ersten vorbestimmten Abschnitt 22 reduziert. Somit ist auch bei niedrigen Temperaturen eine ausreichende axiale Sicherung des Gehäuses 16 gegen axiales Abziehen von dem Außenleiterteil 10 durch die erste axiale Sicherung 20 sichergestellt.At a temperature-induced shrinkage of the dimensions of the housing 16 at low temperatures, the holding force between the claw-shaped elevations 26 and the webs 30 decreases, as well as the width of the webs 30 shrinks. However, at the same time, the holding force between the first predetermined portion 22 of the housing 16 and the elevations 20 increases because the temperature-related shrinkage of the dimensions of the housing 16 also reduces the inner diameter of the housing 16 in the first predetermined section 22. Thus, even at low temperatures sufficient axial securing of the housing 16 against axial withdrawal from the outer conductor part 10 by the first axial securing 20 is ensured.

Insgesamt ergibt sich durch die bei temperaturbedingter Änderung der Abmessungen des Gehäuses 16 gegenläufig wirkenden axialen Sicherungen 20, 22 einerseits (Dehnung) und 26, 30 andererseits (Kompression) ein weiter Temperaturbereich, in dem die mechanische Funktionssicherheit des erfindungsgemäßen HF-Steckverbinders hinsichtlich der axialen Halterung des Gehäuses 16 auf dem Außenleiterteil 10 bzw. dem Bereich 36 sicher gestellt ist.Overall, results from the temperature-related change in the dimensions of the housing 16 counteracting axial fuses 20, 22 on the one hand (elongation) and 26, 30 on the other hand (compression) a wide temperature range in which the mechanical reliability of the RF connector according to the invention with respect to the axial support of the housing 16 on the outer conductor part 10 or the region 36 is ensured.

Das Gehäuse 16 ist als FAKRA-Gehäuse ausgebildet und weist an seinem Außenumfang Erhebungen auf, die einer mechanischen Kodierung 32 zum Zusammenstecken mit anderen Gehäusen 16 sowie als Rastmechanismus 34 zum mechanischen Verbinden von zwei zusammengesteckten Gehäusen 16 dienen.The housing 16 is formed as a FAKRA housing and has on its outer periphery elevations, which serve a mechanical coding 32 for mating with other housings 16 and as a latching mechanism 34 for mechanically connecting two mated housings 16.
